Yunjin Kim, ‘Lost’

Though the producers of ABC’s “Lost” insist they have a master plan, they also seem to insist on keeping their large ensemble cast in the dark as to what that plan is exactly. “Everything about ‘Lost’ intrigues me because you never know what’s going to happen,” says Yunjin Kim, who plays Sun Kwon, the quiet, graceful, bilingual wife to the more volatile Jin Kwon (Daniel Dae Kim), who can only speak Korean. “Whenever we do go back to Sun and Jin’s episodes, there’s always, like, this new secret that keeps on showing (the character to me). It keeps me on my toes.”

Though Kim observes the second season of “Lost” was less about what makes the marooned passengers of Flight 815 tick and more about exploring “what is this island, really more about the storyline than the characters,” it only makes Kim’s impact on the show that much more impressive.

Though Sun and Jin are barely connected to the tangled mythology of “Lost,” their storyline — they were separated for the first eight episodes of the season, then brought closer after Sun is almost kidnapped and later realizes she is pregnant — proved to be a welcome respite of poignant romance amid heavy talk of Dharma Initiatives, mystical numbers and mysterious vaccines.

Plus, the fact that Sun and Jin are growing closer after a prolonged estrangement means that Sun gets to enjoy some newfound freedom. “(Sun’s) very independent right now,” says Kim. “In the pilot, she was told (by Jin) to button her blouse, but nowadays, that’s not a problem within the marriage.”

On the flip side, Kim sees that concentrated time with just one other character as “a blessing and a curse — as far as series regulars, we’re the only couple on the island. A lot of times, I just work with Daniel — who I love working with, but it would be nice to interact with more characters on the island.”

Whether Kim will get that chance remains an open question, since the series has no bones about killing its characters. That hasn’t stopped Kim, who left a successful career in South Korea to make “Lost,” from buying a condo in Hawaii where the show shoots.

Still, Kim’s aware she’s not safe. Since each episode spans just a few days on the island, Kim estimates she won’t have to wear a pregnancy bump until “probably season four — if I’m still around.”

SOUND BITES

Favorite moment of last season?

“(In) the very first flashback with Sun and Jin, at the very last minute they actually bump into each other. I love that moment. I thought it was super sweet (and) what the show is all about, how things were meant to be.”

Favorite shows?

” ‘Grey’s Anatomy.’ ‘Lost’ is such a high-concept, story-driven show, and I think (‘Grey’s’) is the type of show (where) you can miss three or four episodes, just tune in and enjoy that particular episode in itself.”

Underrated actor?

“(It’s a shame that “Lost” co-stars) Michelle Rodriguez and Cynthia Watros got killed off. I would’ve liked to know more about (Watros’ character) Libby before she got shot.”
